MULTI-CHANNEL NETWORK CAMERA SURVEILLANCE SYSTEM AND METHOD OF CONSTRUCTING THE SAME
Provided are a multi-channel network camera surveillance system and a method of constructing the same. The multi-channel network camera surveillance system includes a master network camera including a photographing unit configured to capture an image and a storage unit configured to store first image data of the image captured by the photographing unit; a salve network camera which is connected to the master network camera and configured to capture an image and store second image data of the image captured by the slave network camera in the storage unit of the master network camera; and a client device which receives at least one of the first image data and the second image data from the master network camera.
1 . A multi-channel network camera surveillance system comprising:
a master network camera comprising a photographing unit configured to capture an image and a storage unit configured to store first image data of the image captured by the photographing unit; a salve network camera which is connected to the master network camera and configured to capture an image and store second image data of the image captured by the slave network camera in the storage unit of the master network camera; and a client device which receives at least one of the first image data and the second image data from the master network camera.
2 . The system of claim 1 , wherein the slave network camera does not comprise a storage medium for storing the second image data.
3 . The system of claim 1 , wherein the slave network camera comprises a storage unit configured to store or not to store the second image data according to a user setting, and
wherein, if the slave network camera is set as a slave of the master network camera according to the user setting, the storage unit of the slave network camera is configured to transmit the second image data to the storage unit of the master network camera without storing the second image data in the storage unit of the slave network camera.
4 - 10 . (canceled)
11 . A method of constructing a multi-channel network camera surveillance system which comprises a plurality of network cameras connected to a network, the method comprising:
setting at least one of the network cameras as a master network camera; setting a plurality of slave network cameras connected to the master network camera; and
setting a plurality of slave network cameras at a lower layer which are connected to each of the slave network cameras.
12 . The method of claim 11 , wherein the master network camera comprises a photographing unit configured to capture an image and a storage unit configured to store image data of the image captured by the photographing unit of the master network camera, and
wherein the slave network camera comprises a photographing unit configured to capture an image and does not comprise a storage unit configured to store image data of the image captured by the photographing unit of the slave network camera.
13 . The method of claim 11 , wherein the slave network camera comprises a storage unit configured to store or not to store the second image data according to a user setting, and
wherein, if the slave network camera is set as a slave of the master network camera according to the user setting, the storage unit of the slave network camera is configured to transmit the second image data to the storage unit of the master network camera without storing the second image data in the storage unit of the slave network camera.
14 . The method of claim 11 , further comprising repeating the setting a plurality of slave network cameras at a lower layer.
15 . The method of claim 11 , wherein the setting at least one of the network cameras as a master network camera comprises resetting one of the network cameras as the master network camera based on at least one of a preset order, a size of a network camera address, and a distance from the master network camera to the other cameras in the multi-channel network.
16 . The method of claim 11 , wherein the setting a plurality of slave network cameras at a lower layer comprises setting each slave network camera at a higher layer, to which the slave network cameras at the lower layer are connected, as a master network camera.
17 . A method of constructing a multi-channel network camera surveillance system which comprises a plurality of network cameras connected to a network, the method comprising:
generating a plurality of units, each unit comprising at least one master network camera and a plurality of slave network cameras;
setting at least one of the units as a master unit and setting the other units excluding the master unit as slave units; and
connecting the slave units to the master unit such that the slave units are at a lower layer than the master unit.
18 . The method of claim 17 , wherein the master network camera comprises a photographing unit configured to capture an image and a storage unit configured to store image data of the image captured by the photographing unit of the master network camera, and
wherein the slave network camera comprises a photographing unit configured to capture an image and does not comprise a storage unit configured to store image data of the image captured by the photographing unit of the slave network camera.
19 . The method of claim 17 , further comprising:
generating a plurality of groups, each group comprising at least one master network unit and a plurality of slave network units;
setting at least one of the groups as a master group and setting the other groups excluding the master group as slave groups; and
connecting the slave groups to the master group such that the slave groups are at a lower layer than the master group,
wherein each of the at least one master network unit comprises at least one master network camera and a plurality of slave network cameras, and each of the plurality of slave network units comprises at least one master network camera and a plurality of slave network cameras.
